The San Francisco Chronicle reports (http://bit.ly/1iSDd1M) the social networking giant began chartering a 30-person water taxi Feb. 4 to take employees from San Francisco to Redwood City. The taxi is free and runs round-trip service on Tuesdays and Fridays.
Workers are then taken by bus to the company's campus a little farther south in Menlo Park.
The company told the Chronicle it is testing the ferry service for 90 days.
Google also tested ferry service for employees but abandoned the experiment last week after a month.
The ferry services come as technology companies have faced criticism for running private buses to pick up employees in San Francisco.
